Membrane Trafficking and Signalling

Angelika Hausser

How kinases control membrane trafficking

We investigate how membranes of the secretory pathway are regulated by signal transduction pathways. Here, we are particularly interested in the role of the protein kinase D family. Specifically, we address how external cues control PKD activity and how the kinase engages its interactors and substrates to coordinate the secretory pathway.

Ultimately, we aim at determining the relevance of PKD in cell growth, polarity, migration and invasion, and stem cell maintenance to understand the impact of dys-regulation of PKD signaling and secretion in human diseases such as cancer and neurodegeneration.

microRNAs in cell invasion

Another research area in the lab is the investigation of the role of microRNAs in invasive cell migration. In an image-based screen we have identified miRNAs crucial for invasive migration of human macrophages. We are now particularly interested how these miRNAs regulate the pro-invasive crosstalk of macrophages and breast cancer cells.

Technology platform

We employ an interdisciplinary approach combining 2D and 3D cell culture including primary cells from mice and humans, biochemistry, advanced microscopic techniques e.g. TIRF, FRET, and FRAP, image-based high-throughput screening, and in vivo mouse models.


Our latest research paper "A Rho signaling network links microtubules to PKD controlled carrier transport to focal adhesions" has just been published in eLife! In this paper, we identify a microtubule-regulated Rho signaling network connecting extracellular cues with PKD-controlled secretory transport. The article is available online:
